Succinic acid to tackle acne?

Acne is a multifaceted skin condition influenced by numerous factors, including hyperseborrhoea (excessive oil production), hyperkeratinisation (thickening of the skin), bacterial colonisation (particularly Cutibacterium acnes), and inflammation. These processes result in the creation of blocked pores and subsequent acne lesions. The overgrowth of C. acnes is a crucial factor in the advancement of acne, as it contributes to both inflammation and the formation of pustules or cysts.

Recent research underscores the advantageous role of succinic acid in tackling these fundamental acne mechanisms. Succinic acid, a short-chain fatty acid, is generated during fermentation by commensal bacteria such as Staphylococcus epidermidis present on the skin. This acid has been proven to inhibit C. acnes growth, thus diminishing acne-related inflammation. Topical and intralesional applications of succinic acid have shown efficacy in suppressing C. acnes-induced inflammation both in vitro and in vivo. These findings suggest that succinic acid not only modulates the skin's microbiome but also holds potential as a therapeutic agent in acne treatment, offering a novel approach by utilising bacterial interactions on the skin.

One of the primary advantages of succinic acid is its antimicrobial activity. By suppressing the proliferation of Cutibacterium acnes, the bacteria accountable for acne, succinic acid assists to avert the formation of new blemishes. This action is vital in maintaining a clearer complexion, particularly for individuals susceptible to breakouts. The efficacy of succinic acid in tackling acne originates from its capacity to disrupt bacterial cell membranes through a process termed membrane permeabilisation. This weakens the bacteria, leading to cell lysis and ultimately diminishing the population of acne-inducing bacteria on the skin. This property not only aids in preventing future breakouts but also contributes to an overall enhancement in skin clarity.

Another significant advantage of succinic acid is its anti-inflammatory impact. Acne frequently results in redness and irritation, which can worsen the condition. By integrating succinic acid into our skincare routine, we may witness diminished inflammation, leading to a more tranquil and balanced complexion.

The anti-inflammatory characteristics of succinic acid function by adjusting the immune response, specifically by suppressing pro-inflammatory cytokines and chemokines. This adjustment aids in reducing the redness and swelling linked with acne blemishes. Moreover, succinic acid can stimulate the generation of anti-inflammatory mediators, further boosting its capacity to calm irritated skin. This advantage is particularly beneficial for individuals who suffer from inflamed and irritated skin, as it encourages a more uniform skin tone and texture.

For individuals with oily skin types, controlling sebum production is crucial in managing acne. Succinic acid assists in this regard by balancing oil levels on the skin. By preventing excessive oiliness, we can decrease the probability of blocked pores and subsequent breakouts.

This characteristic of succinic acid is particularly advantageous for those with oily or combination skin types. It operates by regulating the activity of sebocytes, the cells accountable for sebum production. Moreover, by restraining the proliferation of acne-inducing bacteria, succinic acid cultivates a less hospitable environment for these microorganisms, further assisting in the control of sebum secretion. This dual action—managing both oil production and bacterial presence—contributes to the establishment of an optimal environment for clearer skin. By effectively controlling sebum levels, succinic acid tackles one of the fundamental causes of acne.

Succinic acid plays a pivotal role in the exfoliation of the skin, which is essential for averting acne. By gently eliminating dead skin cells and surplus oils from the skin's surface, succinic acid assists in keeping pores unblocked. Blocked pores are a primary contributor to acne flare-ups, and exfoliation aids in minimising this risk by ensuring that the pores remain free of impurities. Succinic acid, when applied in a peel, facilitates this delicate exfoliation process, leading to a smoother and clearer complexion. Regular use of succinic acid exfoliates the skin, removes accumulation, and helps maintain a balanced skin texture, effectively supporting acne prevention.
